Nowadays this is probably the rarest Prodigy release ever. There is the rumour that the promo cassettes were never sent out. The 12" records which were pressed were sent out, but not the cassettes. One copy was given to Jon Carter and one copy to Liam. That means there are atleast 2 existing copies of that testpressing. Jon Carter was the first person outside of The Prodigy/XL Recordings to have it.

Around that time (1996) XL Recordings moved their offices and the cassettes were (mistakenly) thrown in the garbage when they were cleaning up before moving. Some sources says that they were not destroyed by mistake, this was done on purpose.

Mindfields
(December 3rd 1999, Maverick Radio Promo CDR)
01. 03:07 Mindfields (Edit)
02. 03:15 Mindfields (Edit w/ Long Bridge)
03. 03:19 Mindfields (Edit w/ Intro)
04. 03:27 Mindfields Edit w/ Intro & Long Bridge)

The CDR itself is a gold CDR and it has a printed sticker label on it, the text is not printed directly on the disc.

This most likely a release intended for radio play and nothing else since the edits match regular radio edits. If it's Liam or an editer at Maverick who has made the edits is still unclear.
